LASTING h/IACHINE.

SPECIFICATION forming part of Letters Patent No. 696,717, dated April.1, 1902. Application filed April 21, 1900. Serial No. 13,754. (Nomodel.)

To (ZZZ whom it may concern:

Be it known that I, JAMES CAVANAGH, J r., of Brockton, county ofPlymouth, State of Massachusetts, have invented certain Improvements inLasting-Machines, of which the following, read in connection with theaccompanying drawings, is a specification.

This invention is shown and described in the present instance inconnection with the lasting-machine of United States Letters Patent No.584,744, to which reference is had for matters not herein specificallyset forth.

Of the drawings, Figure l is a side elevation of the machine embodyingthis invention. Fig. 2 is a plan of the machine parts which are mostdirectly connected with this invention. Figs. 8 and 4 are also planviews of parts shown in Fig. 2, said views 2, 3, 4 representing theparts in different operative positions.

On the main shaft D of the machine represented in Fig. 1 is a cam 4, bywhich motion is imparted through the lever 5 to effect movement of rod 6endwise against the tension of spring 7, which spring 7 reversely movesthe rod 6 when permitted by cam 4 and at all times keeps thepower-transmitting lever 5 and cam 4 in suitable juxtarelation. The part8 has its shaft-section arranged in the head end of rod 6 for movementendwise against the tension of spring 9. It pivotally supports the pawl10, which pawl has bearing on the stud 12. Pawl 10 is actuated pivotallyby the slide 14 for engagement with ratchet 16 and is then advanced bythe rod 6 for turning said ratchet, and consequently the reel 18, towhich said ratchet is attached, all as referred to hereinafter. Reel 18is employed for holding the Wire 20.

Reference now being had to the above-cited United States Letters PatentNo. 584,744, it will be observed that in the machine of that patent theboot or shoe is prepared for lasting by putting the last in suitableposition relatively to the upper material, lining, 650., and overdrawingthe toe and side portions of said material at the ballot the last andsecuring such overdrawn parts with tacks or other suitable fastenings,which to that end are located and driven through said material and theshoe inner sole, one ineach of said places, a portion of said tacksbeing left projecting as a convenient take-hold for removing said tacksafter the lasting operation has been fully performed. A single pair ofpincers 40 is employed, and the shoe is held by the workman and turnedabout for presenting the difierent parts of the upper to the pincers atdifferent times. Said machine also comprises mechanism for supplying anddriving tacks, whereby the part or section of upper material acted uponby the machine at one time is secured in place upon the inner solepreliminary to the next operation of the machine, the lasting operationas a whole being carried out progressively by repeated operations of themachine applied to different parts of the upper at different times. Itmay be pointed out here as one purpose of this invention to employ thesaid wire 20 in place of said tacks for holding the upper material inplace when lasting certain parts, more particularly the toe parts ofboots and shoes. To this end the workman fastens the outer free end ofWire 20 to tack a. The machine being then started, each successive partof the upper is manipulated into place and held temporarily by thebinding strain of said wire until by repeated operations of the machinethe whole toe part of the shoe is thus lasted around to the tack Z),whereupon the wire 20 is cut and fastened around said tack b. Pressers22 24 are employed for pressing the material into place against thewelt-rib 26. For description of the construction of said pressers andactuating connections therefor see said Patent'No. 584,744. here that inthe operation of the machine one of said pressers remains stationaryagainst the upper, while the other moves backwardly and then forwardlyto press the adjacent section of said upper into place, after which thewire operates for holding the said lasted toe portion of the boot orshoe until the after operation of sewing is completed. Thereupon thewire is removed, and with it the tacks a b. The binding tension of thewire is maintained during the machines operations by causing it to runthrough a gripper device 30. It is to be observed that in the lastingoperations as carried out with this invention, as repre- It may be notedsented in the present instance, different parts of the upper aremanipulated successively into place and simply bound there by the wire20. Said parts of the upper may be manipulated repeatedly wherever theoccasion requires itwithout weakening the material, as might be theresult of such repeated operations when tacks and similar puncturingfasteners are employed. During such operations of the machine as takeplace while the wire-placing mechanism is operative I put a peg in thechannel-groove of the tack-feeding block, whereby tacks are stopped frompassing to the driving mechanisms and the normal action of the machineto fasten the upper with tacks is prevented.

By the method of lasting described above the toe part of the boot orshoe is lasted progressively in one direction from the tacka to the tackb, Fig. 2, and this operation has been proved to yield most admirableresults; but I am aware that by many it is deemed essential to begin thetoe-lasting operations at the point 6, Figs. 3 and 4, which isapproximately near the median longitudinal line of the last, and fromthis point to continue the lasting operations in opposite directions,and this invention is adapted for carrying out the lasting operationsaccording to such plan whenever it is thought desirable so to do. Tothis end the wire 20 is secured, as above described, to the tackf, Figs.3and 4, enough wire being reeled off to allow of the boot or shoe beingpresented to the upper manipulating members, so that the lastingoperations begin at one side of the tack e, from which point thematerial is manipulated in sections progressively toward the tack f. Inthis connection it becomes necessary to take up the slack in wire 20that results from turning the shoe, and consequently moving thetackfstep by step nearer to the reel 18. For this purpose motion isimparted from the cam 4 through lever 5, rod 6, and pawl 10 forbackwardly turning the reel 18, as is required in order to keep theproper tension of said wire 20. In carrying out these operations fromtack e to tackf the upper is manipulated into place progressively byoperations of the pincers 40 and pressers 22 24 without any particularbinding action of the wire 20. The shoe is then moved back to thestarting-point or tack e, during which the said manipulated sections ofupper are drawn into place and tightly bound by the wire 20 from thepoint or tack e to the point or tack h. The lasting operations arecarried out in the manner first above described, the different parts ofthe upper being manipulated and then bound progressively and finallybound by securing the wire 20 to said tack h.

In order to facilitate the understanding of this invention, it may bepointed out here (a fuller description being found in the Patent No.584,744, above referred to) that the presser 24 is allowed to remainstationary and the presser 22 is caused to move for the operations oflasting the toe-part of the shoeu pp er from the point or tack e to thetack or point f, and during this time the slide 14 is in positionagainst the pawl 10 (see Fig. 3) for holding it in engagement withratchet 16, and consequently forcing the operations of cam 4, lever 5,rod 6, and pawl 10 to effectthe above-described; stepby-step movementsof reel 18 for taking up the slack of wire 20. In the operations oflasting from point or tack e to the point or tack h presser 22 isallowed to remain stationary and presser 24is caused to move. In theoperation of the mechanism whereby this changein the action of pressers22 24 is carried out slide 14 is moved endwise to a position, Fig. 2,where it stands remote from pawl 10. Said pawl then assumes the positionshown in Fig. 2, where it remains out of engagement with ratchet 16during the operations of lasting from tack e to tack h, there being thenno back-slacking of wire 20, and consequently no takingup movement ofreel 18. Further, in the machine represented, as more fully described in.said Patent No. 584,744, said pressers 22 24 are brought into and outof action by the workman at will. Hence it is that by starting at thepoint or tack a, Fig. 2, and putting the pressers into operation,.withthe presser 22 remaining stationary, the workman is able by this machineto last progressively in one direction from said tack a to the point ortack b in the manner first above described. The wire-holder 28 ispivotally supported in order that when not in use it may be turned backout of the way and give place for other members of the machine tooperate.
